Serial This invention relates to auditing machines, and more particularly to feeding mechanisms for record strips adapted to be analyzed thereby, and constitutes a division of ap licants co-pending application, Serial l lo. 134,025, filed September 27 1926, now Patent No. 1,818,473.

One object of this invention is to provide a novel means for winding the record on a spool while it is being fe Another object of this invention is to provide a novel mechanism whereby the record material may be fed in one direction or the reverse at the will of the operator.

A further object of this invention is to provide a novel clutch mechanism, which clutch mechanism is effective when the strip is being moved inone direction only.

A further specificobject of this invention is to provide a feeding mechanism, including a spool adapted to have the record material wound thereon and unwound therefrom, connection with a driving means having a given amount of movement for each cycle of movement for turning the spool when the material thereon, and also means for allowing the spool tofbe turned in the opposite direction when unwinding paper there-' from while allowing the driving means to 0perate after the record material, which has been fed by the feeding means, has been wound on said 001.

'. case, Serial No. 134,025, the machine shown therein is adapted to analyze a perforated record strip containing 2,070 classifications.

That case also fully discloses a record carriage and novel mechanism, which is to be the basis of the subject matter of this divisional application, forv feeding such a record strip through the machine to have those 2,070 classifications analyzed. f Due to the great number of classifications thereon, and the particular and novel method of analyzing those classifications, it is very convenient to feed that record strip in two directions, forwardly and backwardl-y, and in order that the operator may not be put to a great deal of unnecessary labor, and in order that much time may be saved during the analyzation of such a record strip, there is 594 has two downwardly 605 when the carriage link 608 connects each provided a novel device whereby through the mere turning of a knob the record strip, after it has been fed in one direction to analyze the classifications by groups, may be cause to run in the reverse direction to analyze other classifications by groups.

Such a novel reversing mechanism enpedites the analyzation of such a record strip, which naturally is quite long, and obviates the necessity of having to rewind the strip before it can be fed through the machine to be analyzed in another direction. In other words, applicants novel mechanism provides for rewinding and at the same time analyzing the strip. It may not be necessary or even desirable to rewind the. complete strip, and the operator may at will reverse the feed of the strip at any time he desires.

Detail record carriage The machine, fully shown and described in the parent case, Serial No. 134,025, is provided with a carriage for feeding the detail record, which has been prepared by another machine, or a summary record which has been prepared by the present machine, through the machine. This carriage is pivoted on a shaft 591 carried by the frames 196 and 202.

The carriage is provided with two main frames 592 and 593 (Figs. 1 to 5) which are secured together by two cross members 594 and 597. The frames 592 and 593 are loosely mounted on the shaft 591. The cross member projecting flanges 595 which are threaded to receivc ashort screw member 596, the purpose of which will be hereinafter described. The frames 592 and 593, together with the cross members 594 and 597, form the frame work for supporting the analyzer drum and the spools for supporting the records. The frame 593 has secured thereto an auxiliary frame 599 between which the driving mechanism for the carriage is supported.

A means is provided for latching the carriage in a position in the machine so that the analyzer contacts accurately engage the perforations in the detail record, and also to provide a means for accurately meshing a driving gear which is mounted in the carriage with a driving'gear in the machine.

Mounted on each of the frames 592 and 593 (Figs. 1, 4 and 5) is a stud 605. Pivoted on a shaft 606 carried by the frames 195 and 196 are two bell cranks 607 which are notched at their right hand ends to surround the studs is in the machine. of the bell'cranks 607 to an arm 609 secured to a shaft 610 carried by the frames 195 and 196. Also secured to the shaft 610 (Fig. 7 is a lever 611 having pivoted thereto a latch 612. The latch 612 is adapted to engage notches 613 out into the periphery of a disk 614 carried by the frame 196. A spring 615 stretched between a stud 616 on the latch 612 and a stud 617 on the lever 611 normally holds the latch 612 in engagement with one of the notches 613.

When it is desired to rock the carriage 590 about its pivot 591, it is necessary to disengage the latch 612 from the notch 613, and then rotate the lever 611 so that the latch 612 will engage the foremost notch 613 (Fig. 7). This movement of thelever 611 rocks the shaft 610 counter-clokwise (Figs. 4 and 5) to rock the bell cranks 607 in a counterclockwise direction by means of the link 608 to disengage them from the studs 605. The carriage 590 is then free to be rocked in a clockwise direction about its pivot 591 in order to permit the operator to, either remove the analyzed record from the carriage, or, to

place a new record thereon in a manner to be presently described.

Analyzer drum alz'm'ng device The analyzer drum which will be hereinafter described, is mounted on a shaft 620 (Figs. 1, 4 and 5) carried by the carriage frames 592 and 593. It is desired to lock the analyzer drum against rotation when the carnage is rocked about its pivot 591 as just described. An aliner pawl 621 (Figs. 1 and 5) is provided which is pivoted on the left hand stud 605 secured on the frame 592. The pawl 621 is provided with a flange 622 which is adapted to engage a notch 623 in a disk 624 secured to the above mentioned shaft 620. There are siX notches 623 provided in the disk 624. The reason for this, is that one step of movement of the detail record is equal to one-sixth of'a rotation of the shaft 620. A spring 625 is stretched between a stud 626 on the pawl 621 and a stud 627 carried by the frame 592. The spring 625 normally tends to rotate the pawl 621 in a clockwise direction but is prevented from doing so by a stud 628 carried by one 'of the left hand bell cranks 607 (Fig. 1). However, when the bell crank 607 is rotated to disengage it from the stud 605 as above described, the stud 628 is moved away from the pawl 621 to permit the spring 625 to rock the flange 622 into one of the notches 623. When the flange 622 is in one of the notches 623 and the carriage is rocked about its pivot 591, the analyzer drum which is mounted on the shaft 620 is held against rotation.

It is desired to prevent the carriage from being rotated about its pivot 591 until the pawl 621 is entirely engaged with one of the notches 623. The pawl 621 is provided with be entirely free from the stud 630. When the flange 622 is entirely engaged with one of the notches 623, the flange 629 is disengaged from the stud 630.

p A means is provided for preventing the detail carriage from being acted upon by grav- 5 ity, which action would give acceleration'to the carriage when it is rocked about its pivot 591 (Figs. 1, 2 and 4). Surrounding the shaft 591 is a sleeve 635.. The above mentioned screw members 596 are provided with short hubs 636. A powerful spring 637 surrounds the sleeve 635 and is carried by the hubs 636 of the screw members 596. The spring 637 exerts constant pressure against the screw members 596. The screw membersare threaded in cpposite directions from each other, that is, one has right-hand threads, and the other left-hand threads. When the carriage 590 is rocked about its pivot as above described, the threaded flanges 595 force the screw members 596 toward each other to compress the powerful spring 637. The spring 637 is adjusted to permit the carriage, by means of its weight, to rock a certain distance, whereupon the force exerted by the spring overcomes the weight of the carriage, and therefore prevents further movement thereof. I

The tension of the spring 637 can be adjusted by means of a member 638 (Fig. 1) 4 which is pinned to the shaft 591. The member 638 is provided with five holes 639, only one of which is shown. The frame 196 is provided with a tapped hole 641 adapted to receive a. screw 642, which projects through one of the holes 639. If the spring 637 is not properly tensioned, it can be adjusted by rocking the member 638 either up or down to reglster one of the holes 639 with the tapped hole 641 and inserting the screw 642 therein tion. This movement of the shaft causes the screw members to be moved either toward or away from each other, thereby regulating the tension of the spring.

Analyzer drum As above mentioned, the shaft 620 has secured thereto an analyzer drum 645 (Figs. 1, 2, 4 and 7). The drum 645 is provided with two flanges 646 which are pinned to the shaft 620. The drum 645 is insulated from the flanges 646 by circular bands of insulation 647. The flanges 646 are provided with spurs 648 which are adapted to engage square holes 649 (Fig. 1) in tne record strips. It will be noticed that the holes 649 on the left-hand side of the strips are equally spaced, and the holes on the right-hand side have every fifth perforation omitted. The flanges 646 of the drum 645 are provided with spurs 648 equally spaced on the left-hand side, and with every fifth spur omitted on the right-hand side. The object of'spacing the holes'in the record and the spurs on the drum in this-.manner,

to hold the member 638 in its adjusted posi-- record on the carriage.

Detail paper tension roll It is desired to hold the record strip tightly against the drum as it is being fed through the machine to be analyzed. Looselymounted on the shaft 610 are two arms 650 (Figs. 4, t

5 and 7), which carry a shaft 651 upon which is mounted a roller 652. Pivoted to a stud 653 on each of the above mentioned arms 609, is an arm 654 which carries a shaft 655 upon which is mounted a roller 656. A spring 657 is stretched between a stud 658 carried by the arm 650 and a stud 659 carried by the arm 654 and normally draws the arms 650 and 654 toward eachother. The drum 645 over which the detail record is fed lies in the path of the two rollers 652 and 656, and therefore the spring 657 holds them tightly against the drum. 645.

When it is desired to rock the carriage about its pivot to change the record it is necessary to rock the roller 656 out of the path of the drum 645. It will be remembered that a means is provided for rocking the shaft 610 to disengage the bell crank 607 from the stud 605 to unlock the carriage 590. When the shaft 610 is rocked, the arm 609 by means of the stud 659, rocks the arm 654 in a counterclockwise direction about the shaft 610 to permit the carriage to be rocked from the machine.

It will be noticed that the slots through which the stud 659 projects is elongated. This elongation is to permit relative motion between arm 609 and the arm 654, and-also to permit the spring 657 to hold the roller 656 tightly against the drum 645, as above described.

Four plates, two of which are shown at 660 (Fig. 4), are held against the drum 645 and act as strippers to loosen the record from the analyzer drum. This is necessary because since the rollers 652 and 656 cause the record to be tightly held against the drum, it has a tendency to adhere to the drum and be wound thereon.

Detailpaper spools The carriage is provided with two spools which are adapted to be rotated in either direction. The detail record may be placed on either of these spools. The feeding mechanism is controlled in a manner to be hereinafter described, so that the record may be Formed on a shaft 668 slidably mounted in the frame 592 of the carriage is hub 669 having secured thereto a flange 670. Each of the hubs 666 and 669 is provided with notches 671 (Fig. 2) into which flanges flange 667.

672 of a tube 673 project. The tube 673 is provided with a slot 674 extending its full length to provide a means for attaching the end of the detail record. The end of the detail record is inserted into the slot and then it is given a few turns around the cylinder with those above described for shafts 665 and 668. A tube 673 is supported'by the shafts 675 and 676 in identically the same manner as the shafts 665 and 668 support the first p mentioned tube 673.

The shafts 668 and 67 6 are slidably mounted in the frame 592 but are held in their positions by pivoted members 680 (Figs. 1 and 8). The shafts 668 and 67 6 are notched to permit projections 681 of the pivoted members to engage therewith. The projections 681 are held in engagement with the notches by a spring 682 stretched between studs 683 on the pivoted members.

In order to remove one of the tubes67 3 for the purpose of either removing or placing a record thereon, it-is'necessary to rock one of the members 680 to disengage the projection 681 from the notch in the shaft,668. Each of the shafts 668 and 67 6 is provided with a knob 684 to permit manual rotation of the shafts or to permit the shafts to be moved laterally in their hearings in the frame 592 to disengage the 672 of the tubes 673, thereby permitting the operator to remove the tube from the carriage.

Feeding mechanism As previously stated the record is adapted to be fed in either direction. The object is to provide a simple means of feeding the record repeatedly through the machine for analyzing without the necessity of taking the record out of the carriage and replacing it on the original spool from which it has been fed. In the present machine this isparticularly desirable, because only certain transactions of the record are analyzed each time the record is sent through the machine. When the machine is adjusted to selectcertain transactions. the feeding mechanism is controlled, whereby it feeds all other transactions past the analyzer without stopping. The means for thus controlling the movement of the record will be hereinafter described.

" a circular flange 703 hubs 669 from the flanges Secured to the shaft 620 is a gear 690 (Figs. 1, 2 and 3) which is adapted to be rotated by mechanism to be presently described. The gear 690 meshes with a gear 691, loosely mounted on a shaft 692. The ear 691 meshes with a pinion 693 secured to a shaft 694 carried by the frames 593 and 599. The pinion 693 meshes with a gear 695 loosely mounted on a shaft 696 journaled in the frames 593 and 599. Also loosely mounted on the shaft 692 is a gear 697 which is adapted to be driven'by the gear 691 by means of a clutch to be presently described, when being rotated in one direction. The gear 695 is adapted to drive a gear 698, which is loosely mounted on the shaft 696 by a clutch mechanism, in one direction. The gear 697 meshes with a pinion 699 loosely mounted on the shaft 675 and the gear 698 meshes with a pinion 700 loosely mounted on the shaft 665.

Assuming that the detail record has been laced on the lowermost spool, carried by the shaft 665, as shown in Figs. 1 and" 3, and is being fed onto the upper spool carried by the shaft 675, the gear 690 is rotated in a clockwise direction (Fig. 3). Clockwise movement of the gear 690 rotates the gear 691 in a counter-clockwise direction. Secured to the gear 697 is a clutch member 701 which is secured to the shaft 692 by means of a pin 702. -The gear 691 is provided with into which the clutch member 701 projects. positioned between the flange 703 and the clutch member 701, and is held in this position by a flat spring 705 mounted on the clutch member 7 01. The clutch member 701 is so shaped thatwhen the gear 691 is rotated in a counter-clockwise direction, the roller 704 is wedged between the flange 7 O3 and the 706 which is held against another friction plate 707 by=meansof a spring 708. The spring 708 holds the pinion 699 against another friction plate 709. The friction plates 707 and 709 are both secured to the shaft 675. 'When the pinion 699 is rotated in a clockwise direction, as above mentioned, the shaft 675 is carried therewith by means of the friction plates 707 and 709.

When the gear 691 is being rotated in a counter-clockwise direction, as just described, the pinion 693 is rotated clockwise and thereby rotates the gear 695 counter-clockwise. The gear 695 is provided with a flange 7 03, as above described for the gear 691. Secured to the gear 698 is a clutch member 701. Disposed between the fiange 7 03 and the clutch member 701 of the gears 695 and 698 is a roller 704 which is held in position by a spring identical in construction, the only diiference being that they are arranged to drive their respective gears in opposite directions. When the gear 695 is being rotated counterclockwise, the flange 703 on the gear 695 tends to rotate the roller 704 away from the clutch member 701, and therefore the gear 695 rotates independent of the gear 698. However, when the direction of rotation of the gear 690 is reversed to feed the detail rec-v ord in the opposite direction from that above described, the gear 695 is rotated in a clockwise direction, and therefore, by means of the roller 704, the clutch member 7 01 rotates the pinion 700 in a counter-clockwise direction. The shaft 665 also has friction plates 7.06, 7 07 and 709 mounted thereon, and a spring 708 for holding the plates 706 and the pinion 700 against the friction plates 707 and 709, as above described. 7

From the above description it can be seen that no matter in what direction the gear 690 is rotated, the clutch members adapt themseves to drive their respective pinions to feed the record material in either direction; that is, if the gear 690 is being rotated in a clockwise direction, the upper clutch membrr on the shaft 692 rotates the shaft 67 5 in a clockwise direction to feed the record on the spool which is connected to this shaft. When the gear 690 is rotated in a counter-clockwise direction, the lower clutch member 7 01 rotates the shaft 696 to drive the pinion 700 in a counter-clockwise direction to feed the record material on the spool that is connected to the shaft at 665.

The object of providing the shafts 665 and 675 with friction drive as above described, is to provide a means for taking care of the variable amount of feed required for feeding the record on the spool as the diameter of the-record on the spool increases. The amount of movement of the gear 690 for feed- ;ing the record material for .one transaction is fixed. but the angular rotation of the shafts 665 and 67 5 varies withthe diameter of the paper on the spool. When the spool, as illustrated herein, is completely filled, the angular movement of the shaft 67 5 necessary to take up the amount of feed required for one transaction is 42. When the spool is emptied the angular movement required is 180 The ratio of the gears 690 and 691 and pinion 699 is such that one step of movement ofthe gear 690 rotates the pinion 699, 180. It can, therefore, be seen that the pinion 699 has a fixed angular movementfor each transaction, whereas the angular movement of the roll itself will vary from 42 to 180, and there- -fore, a maximum slippage of 138 is required. When-the record is being wound. upon the spool 67 5, it is being unwound from the spool on the shaft 665, and vice versa. The unwinding of the paper from the spool is accom= plished by the drum 645 and the spurs 648 there-on. It can therefore be seen that when the paper is being fed by the drum, it is being pulled from one of the spools. In order to prevent the paper from unwinding too rapidly, a means is provided whereby a braking effect is applied on thespool that is being unwound. It will be remembered that the pinion 7 00 for the shaft 665 meshes with the gear 698. The gear 698 has a hollow hub 715 (Fig. 2). The shaft 696 has'a shoulder 716 against which a spring 717 exerts pressure. The other end of the spring 717 exerts 7 pressure against the inside of the hollow hub 715 of the gear 698. From this it can be seen that friction is set up between the right-hand end of the shaft696 and the frame 599 of the record carriage, and between the hub 715 of carriage. The friction set up by the spring 717 is suflicient to prevent the record from unwinding from the spool too rapidly.

The shaft 692 for the upper-spoolis provided with a similar spring 717 which sets up friction to act as a brake for the upper spool when the record is being unwound from thatspool.

Detail record feed control .the detail record is to be fed. Secured to the shaft S, which shaft is described in the parent case, Serial No. 134,025, as the short cycle shaft, is a gear 718 (Figs. 9 and 12) which is mounted 'on a hub 719 together with a disk 720. Mounted between the gear 718 and the disk 720 are five studs 721 which are adapted to engage notches 722 on a Geneva plate 723 secured to a shaft 724. Also se-. cured to the shaft 7 24 is a clutch member 725 (Figs. 10, 11 and 12). Loosely mounted 011' the shaft 724 are two beveled gears 726 and 727 which are spaced from each other by a sleeve 728 and upon the shaft by a sleeve .7 29. Disposed between the beveled gears '726 and 7 27 and meshing therewith, is a beveled pinion 730 carried by a bracket 731 mounted on the side frame 196. Secured to the beveled gear 727 is a gear 7 32 in mesh with the abovev mentioned gear 690, when the record carriage is rocked'into position for having the record analyzed.

With the clutch member 7 25 in the position shown in Fig. 11, the shaft 724 receives a clockwise rotation (Fig. 9) by means of the shaft S, the studs 721 and the Geneva plate 723 secured thereto. The clutch drives the beveled gear 726 in a clockwise direction, and by means of the beveled pinion 7 30 rotates the beveled gear 7 27 and gear 7 32in a counteragainst lateral screw member 735 loosely mounted there on. The member 735 has a pinion 736 made integral therewith, both of which are held movement on the shaft 724 by means of 'a collar 734 secured to the shaft and the shoulder formed by the portion 733. Secured to the frame 196 is a bracket 737 which is threaded to receive the screw member 735. Meshing with the pinion 736 is a wide gear 738 mounted on a short stud 739 carried by the frame 196. The gear 738 is made wider than the pinion 736 to permit the pinion and the shaft 724 to be shifted laterally in a manner to be hereinafter described. Meshing with the gear 738 is a gear 740 (Figs. 10 and 12) which is secured to a shaft 741 carried by the frames195 and 196. Secured to the shaft 741 is a knob 742 which projects through the cabinet 710 of the machine. The knob 7 42 is provided with a pointer 743 to enable the operator to determine in what position the knob is set.

When it is desired to reverse the direction of feed of the detail record, the operator must turn the knob 742 counter-clockwise, 180 (Fig. 9), until a shoulder 7 44 on a disk 745 secured to the shaft 741, engages a stop der 744 by means of a 746 on an arm 747 pivoted on th shaft 450. The stop 746 is held in the path of the shoulspring 748 stretched between a stud 749 on the arm 747 and a stud 750 carried by the frame 196.

When the knob is turned in a counter.- clockwise direction, as just mentioned, the gear 7 40 rotates the gear 7 38 clockwise, which rotates the pinion 736 in a counter-clockwise direction. The pinion 736 thereupon is moved to the right (Fig. 11) by the screw member 735 and the threaded bracket 736 to shift the shaft 724 toward the right. This shifting movement of the shaft 724 disengages the clutch member 725 from the beveled gear 726 and engages it with the beveled gear 27. The studs 721 located between the gear 718 and the plate 720, are long enough to permit the Geneva plate 723 to shift with the shaft. With the clutch member 725 engaging the beveled gear 727 andthe shaft 724 given a clockwise rotation as above mentioned, the beveled gear 7 27 and the gear 7 32 are-rotat ed clockwise.

i 769.0{intheipaper'carriage in a counter-clock- This rotates thegear fwise directioni which is the reverse of that fabove described.

If it is desiredto again reverse the direction of the feed, the operator must turn the knob '732 in a clockwise direction until a shoulder 751 engages a stop 746 in the arm 747. This brings the mechanism back to the positionshown in Fig. 9.

In order that the perforations on the record strip will always be in proper alinement for analyzation, the shaft 620 (Fig. 6) to which the analyzer drum 645 is secured, carries a disk 1055 provided with notches 1056'. Once during each analyzing cycle of operation an aliner arm 1050 secured to the shaft 606 is adapted to engage one of the notches 1056 to properly alin-e the perforations when the analyzer contacts shown in the upper part of Fig. 12 are brought into contact with the record sheet to analyze the same.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.

What is claimed as new, is:

1. In a machine of the class described, the combination of feeding means for feeding record material a given amount for each cycle of operation, a spool adapted to have record material wound thereon or unwound therefrom, driving means having a given amount of movement for each cycle of movement for turning said spool when winding material thereon, a friction drive between said driving means and spool to allow the driving means to operate after record material which has been fed by the feeding means has been wound on said spool, and another friction means to prevent said driving means from turning said spool when record material is being unwound therefrom by said feeding means.

2. In a machine of the class described, the combinationof feeding means for feeding record material a given amount for each cycle of operation, a spool adapted to have record material wound thereon or unwound therefrom, driving means having a given amount of movement for each cycle of movement for turning said spool when winding material thereon, a friction drive between said driving means and spool to allow the driving means to operate after record material which has been fed by the feeding means has been woundon said spool, and means for preventing said driving means from turning said spool when record material is being unwound therefrom by said feeding means;

. 3; Ina machine of the class described,- the combination of means for feeding record material a given amount for each cycle of operation, spools adapted to have record material wound thereon and therefrom, a common driving means for said spools adapted to drive said spools in either direction, and means for clutching said driving means to said spools for winding the record thereon, one element of said clutching means acting as a brake for said spools when unwinding the record material therefrom.

In testimony whereof I aflix my signature.
